Title: Waste paper treatment process
Inventor: BLAIN TERRENCE J
IPC: D21H11/14
Filed: 1993-06-02
Abstract: A waste paper treatment process for the recycle and re-use of waste paper, which process comprises treating the waste paper , in a repulper, with a surfactant, preferably in the absence of traditional repulper chemicals such as silicate, caustic and peroxide.  The surfactant is preferably a copolymer of ethylene oxide and propylene oxide, and is used in a sufficient concentration to form ink agglomerates which are retained on the paper as essentially non-visible agglomerates, rather than being removed from the recycled pulp as in traditional waste paper deinking. The process permits the elimination of normal repulper chemicals, and reduces the amount of ink sludge generated, while providing acceptable brightness levels for the recycled pulp.

Title: Solid state imager
Inventor: CHIULLI CARL A
IPC: G03C8/10
Filed: 1993-06-17
Abstract: A filter is formed on a solid state imager by: forming, on the imaging surface of the imager, an adherent layer of a dye-con-taining photoresist composition comprising a photoresist resin and a thermochromic dye, this dye being substantially non-absor-bent of actinic radiation of a first wavelength, but capable, upon heating, of undergoing a thermally-induced color change which renders it absorptive of actinic radiation of the first wavelength; imagewise exposing the adherent layer of dye-containing photo-resist composition to actinic radiation of the first wavelength; removing one of the exposed and unexposed areas of the layer, while leaving the other of the exposed and unexposed areas on the imaging surface, to form a pattern of filter elements; and heat-ing the solid state imager to a temperature and for a time sufficient to cause the dye to undergo its color change, thereby causing the filter elements to become absorptive of radiation of the first wavelength. This process avoids the long exposure times other-wise required when forming filter elements of a color which strongly absorbs the exposing radiation.

Patent CA-2148649-A1 (CA)
Inventor: MANKE KEVIN P
IPC: E21B41/00
Filed: 1995-05-04
Abstract: An improved mechanical system selectively locks the tester valve of an annulus pressure responsive tester valve in position for an indeterminate number of well annulus pressure cycles.  The tester valve can be closed upon demand. The forces which accomplish opening of the ball valve act across a power piston, but the forces which close the valve act across an actuating piston. The tester valve can be run into a well with an operating element of the tester valve such as a tester valve, in a first position such as a closed position. Upon reaching the desired depth within the well and setting of an associated packer system, well annulus pressure is then increased to a first level above hydrostatic pressure to move the power piston and thus move the tester valve to an open position. During a normal mode of operation, well annulus pressure can be cycled between hydrostatic pressure and the first level to open and close the tester valve. If desired, the tester valve may be placed into a "locked open" mode of operation wherein the well annulus pressure can be cycled between hydrostatic pressure and the first level, such as would be done to operate a pressure annulus device elsewhere in the testing string. To place the tester valve into the "locked open" mode, a second level of well annulus pressure, which is above the first level, is applied to the well annulus and then released. Reapplication and release of the second level of annulus pressure will enable a selectively actuatable load transfer assembly to close the associated ball valve and return the tester valve to its normal mode of operation.     A fluid transfer assembly is included within the power piston which is operable to transfer fluid across the power piston. The fluid transfer assembly includes a pressure relief valve and fluid restrictor which will transfer fluid in one direction across the power piston in an overpressure condition when the well annulus pressure is increased to a second level above the first level.  The fluid transfer assembly also includes an oppositely disposed check valve to allow unrestricted fluid flow across the power piston in the opposing direction during a release of annulus pressure. The tester valve also features a multi-range metering cartridge which is operable to meter fluid over a wide range of differential pressures. The metering cartridge provides an adjustable resistance flow path which permits fluid flow across the cartridge. The resistance of the flow path is adjustable by selectively diverting the fluid through a series of fluid flow resistors.  Resistance may be increased either by adding a number of flow resistors serially or by adding a single flow resistor which itself provides a greater fluid flow resistance.

Title: Pultruded part with localized regions of different resin materials
Inventor: DAVIES LAWRENCE W
IPC: B29C70/08
Filed: 1993-11-26
Abstract: A pultruded part (23) is formed from thermo-setting resin (19) which is carried on continuous longitudinal fiber reinforcement (13, 15) into a die (20) which shapes the resin and fibers into the required transverse cross sectional shape and then acts to set the resin. Some of the fibers (15) have applied thereto a second resin material (26) of a different characteristic so that these fibers carry the second resin into the part at localized regions to form localized regions (40, 41, 42, 43, 44, 45) of the second resin extending longitudinally continuously of the part.  This allows a resin of an increased strength to be used at areas of increased strength requirement, for example areas of screw fastening, screw ports, junction between two legs and in order to provide a thinner part for reduced thermal transfer.
